Drop discs and line up four: keep a streak alive against an Easy, Medium or Hard AI, or challenge a friend on one device.

How to play

Line up four of your discs horizontally, vertically or diagonally to win the round.
Click or tap a column to drop your coral disc. A preview disc shows where it will go. On a keyboard, pick a column with the Left/Right arrows or keys 1–7 and drop it with Enter, Space or Down.
Solo: a round win scores +3 and a full board (draw) +1. Starting turns alternate every round. One loss ends your streak.
Easy makes mistakes, Medium always blocks a direct threat, Hard looks six moves ahead. The last disc played is ringed so you can see the computer's reply.
In Duo mode, Coral and Lime take turns on one device; the first to win 3 rounds wins the match. Undo (or U) takes back the last disc of the round.
Your run is saved after every move: use Continue on the menu to pick it up later.

About Four in a Row

Four in a Row turns the gravity-drop classic into a streak challenge. Drop your coral disc into one of seven columns and it falls to the lowest free slot; four of your discs in a row, column or diagonal wins the round. Every win against the computer is worth 3 points and every draw 1 point, and the first loss ends your run. Easy plays loosely and only sometimes blocks, Medium always blocks a direct threat but can be out-planned, and Hard looks six moves ahead. Starting turns alternate every round, so you will have to defend as well as attack. Duo mode is a first-to-three match for two players sharing a phone, tablet or keyboard, with an Undo button for mis-taps.
